Denise Richards (L) and Tracy Morgan film a scene at the "30 Rock" movie set at Rockefeller Center on October 17, 2011 in New York City.
The guest starring effort comes just as Denise recently opened up about her decision to adopt a baby girl despite the fact that she is single.
"I had always wanted more children," she wrote in a blog post earlier today. "I needed to make a decision: Do I wait for the right partner or move ahead with my life and do it on my own? I decided to do it on my own."
Richards went onto explain that the adoption process took two years, which left her feeling defeated at times.
"But I always had faith that the right baby would find us," she wrote. "I've always felt that children choose their parents, and Eloise found me a different way."

Reality hits

Richards' daughters appear on the actress's E! reality show, "Denise Richards: It's Complicated." Although their father, Charlie Sheen, was against the kids being on the program, Richards took the matter to court and won. Richards recently told Larry King, however, that the kids are in the show "very little."

Richards, unscripted

Don't all nuclear scientists look like this?

charlie sheen
has had a drug problem. same with
brookemueller
. as part of the custody agreement both parents must take random
drug tests
.
brooke
failed to take one so
sheen
flew to l.a. and made a plea to the judge calling
brooke
an unfit mother.
charlie sheen
arrived to court tuesday with his so-called goddess natty ready to do battle with
brookemueller
.

>>i feel terrific, thank you.

>>there was always drama between the two of them. now that
brooke
has fallen off the wagon it's given
charlie
an in.

>> reporter: at stake, custody of the 2-year-old twins, bob and max. in the private hearing,
sheen
argued that
brooke
violated their custody agreement by refusing to take a
drug test
last week that he deserves the children
full time
.

>>she knows the rules and the consequences are radical. i told her don't pick a [ bleep ] fight with a warlock because you're going to lose.

>> reporter: charlie
versus
brooke
. it's been brewing for months. so messy even
denise richards
offered to take in the twins. the children keep getting bounced around. in early march officers showed up at
sheen
's mansion and removed them. under a
court order
filed by
brooke
, hours later,
sheen
spoke with me in a live interview on "today."

>>there is nothing to hide and nothing but love and compassion and support for the amazing children.

>> reporter: charlie
and brook finally reached a custody deal.
sheen
gets alternate weekends and some weeknights and both parents have to take random
drug tests
. just last week tmz posted this video from a california pawnshop showing

drug test

brooke
admitted to the judge she's back in outpatient rehab. but it wasn't enough. in a defeat for
charlie sheen
, the judge did not award him full custody. instead, keeping the agreement as is. bob and max will continue living with
brooke
and her mother in california.

>>the court is not going to change custody because of the fact that ms.
mueller
is in rehab. but i don't think that anyone should assume that this is going to be something that the court will be indifferent to should it happen again. [ cheers and applause ]

>> reporter: by late tuesday night, after his loss in court,
sheen
was back on the
east coast
, performing his one-man show in washington, d.c. and he had lots to say about the hearing.
